Answer:

AC ≈ 23.6 units

Step-by-step explanation:

m∠CAD = 90°

CD = 2×14 = 28 , AD = 15

CD² = AD² + AC² ⇒ AC² = CD² - AD²

AC² = 28² - 15² = ( 28 - 15 )( 28 + 15 ) = 13 × 43 = 559

AC ≈ 23.6

A relationship might exist in a sample even though it does not exist in the population, because of b) Sampling error

In statistical analysis, a relationship might appear in a sample even though it does not exist in the population due to sampling error. This occurs when the sample is not fully representative of the population, leading to discrepancies between the sample statistics and the true population parameters.

Sampling error can cause random fluctuations that mistakenly suggest a relationship, which may not be present in the larger population. It is important to consider the limitations and potential sources of error when generalizing findings from a sample to the broader population. So b option is correct.

The height of the 10th bounce of the ball will be 0.6 feet.

A geometric sequence is a sequence in which each term is found by multiplying the preceding term by the same value.

The nth term of the geometric sequence is given by

\(\sf T_n=ar^{n-1}\)

Where,

According to the given question.

During the first bounce, height of the ball from the ground, a = 4.5 feet

And, the each successive bounce is 73% of the previous bounce's height.

So,

During the second bounce, the height of ball from the ground

\(\sf = 73\% \ of \ 10\)

\(=\dfrac{73}{100}(10)\)

\(\sf = 0.73 \times 10\)

\(\sf = 7.3 \ feet\)

During the third bounce, the height of ball from the ground

\(\sf = 73\% \ of \ 7.3\)

\(=\dfrac{73}{100}(7.3)\)

\(\sf = 5.33 \ feet\)

Like this we will obtain a geometric sequence 7.3, 5.33, 3.11, 2.23,...

And the common ratio of the geometric sequence is 0.73

Therefore,

The sixth term of the geometric sequence is given by

\(\sf T_{10}=10(0.73)^{10-1\)

\(\sf T_{10}=10(0.73)^{9\)

\(\sf T_{10}=10(0.059)\)

\(\sf T_{10}=0.59\thickapprox0.6 \ feet\)

Hence, the height of the 10th bounce of the ball will be 0.6 feet.

Uncontrollable factors can have an effect on the result of a scenario or experiment. Here are a few strategies for dealing with such factors:

Recognize the variables, Reduce the impact, Randomization, Statistical analysis, Concentrate on what you can control.

Recognize the variables: The first stage is to identify the uncontrollable elements and acknowledge their possible effect on the result. This allows you to plan for unexpected events and alter your expectations accordingly.

Reduce the impact: Even if you can't control the circumstances, you can reduce their influence by taking particular activities. For example, if weather conditions may have an impact on the result of an outdoor event, you may want to arrange it during a more favourable time of year.

Randomization: When dealing with uncontrolled elements in a scientific experiment, randomization can assist in evenly distributing the impact of these factors among multiple groups.

Statistical analysis: In data analysis, statistical analysis can help to account for the impact of uncontrollable factors. Statistical models can provide more accurate estimates of the influence of a given variable by controlling for other variables and accounting for the variability produced by uncontrolled factors.

Concentrate on what you can control: In many circumstances, it is more productive to focus on what you can control than than fretting about what you can't. You may be able to mitigate the effects of uncontrollable elements to some extent by recognising and maximising the controllable factors.

Step-by-step explanation:

The change in profit (ΔP) when the number of units (Δx) increases by 5, based on the given marginal profit function, is -18331.50

To find the change in profit (ΔP) when the number of units (Δx) increases by 5.

we need to evaluate the marginal profit function and multiply it by Δx.

The marginal profit function is given by dP/dx = 12.1(60 - 3x).

We are given the value of x as 121, so we can substitute it into the marginal profit function to find the marginal profit at that point.

dP/dx = 12.1(60 - 3(121))

= 12.1(60 - 363)

= 12.1(-303)

= -3666.3

Now, we can calculate the change in profit (ΔP) by multiplying the marginal profit by Δx, which is 5 in this case.

ΔP = dP/dx×Δx

= -3666.3 × 5

= -18331.5

A sampling distribution, also known as a finite-sample distribution, in statistics is the probability distribution of a given random-sample-based statistic. The sampling distribution is the probability distribution of the values that the statistic takes on if an arbitrarily large number of samples, each involving multiple observations (data points), were used separately to compute one value of a statistic (such as, for example, the sample mean or sample variance) for each sample. Although only one sample is frequently observed, the theoretical sampling distribution can be determined.

Because they offer a significant simplification before drawing conclusions using statistics, sampling distributions are crucial in the field. They enable analytical decisions to be made based on the probability distribution of a statistic rather than the combined probability distribution of all the individual sample values

The AREA of the parcel of land area is 14382 sq yd nearest square yard

We can see that the parcel of land is an isosceles triangle with two 45-degree angles. Therefore, the triangle is a 45-45-90 triangle, and the length of each leg is equal to x (say).

We know that the longest side (hypotenuse) is approximately 240.42 yards. Using the relationship in a 45-45-90 triangle, we can write:

longest side = x√2

240.42 = x√2

x = 240.42/√2

x ≈ 169.71

Therefore, the length of each leg is approximately 169.71 yards.

To find the area of the triangle, we can use the formula for the area of a triangle:

area = 1/2 * base * height

In a 45-45-90 triangle, the base and height are equal (since the triangle is isosceles), so we can use either leg as the base and height.

Using x = 169.71 as the base and height, we get:

area = 1/2 * 169.71 * 169.71

area ≈ 14382.42

Rounding to the nearest square yard, we get: area ≈ 14382 sq yd.

and shoes were originally priced at $72.50 and that a 6.5% sales tax will be applied.

On Double Dribbles, the same shoes were on for $54.75, and a 9% is added and has an extra $5.99 for shipping.

i.e. we  have to find the difference in the total costs..

Now we have to multiply 12 by 72.50. The answer to that is 870. Next, we need to multiply 8 by 870 and divide it by 10. The answer to that is 696. Then, we need to add the price and the tax. The price will be 100%, and the tax will be 6.5%. 100 + 6.5 = 106.5. After that, we need to 106.5 by 100. The answer it that is 1.065. Now do  times 1.065 by 696. And the answer to that is $741.24.

Do the same for other store.  The answer to it is 788.01.

NAME OF THE BONE UNDER SHOULDERS

Answer:

Humerus

Step-by-step explanation:

The marginal probability density functions of X and Y are both uniform on the interval [-1, 1]. X and Y are not independent because the joint distribution depends on the constraint x² + y² ≤ 1. The covariance of X and Y is zero, indicating that they are uncorrelated. The probability of X being less than or equal to Y can be computed as 1/4.

(a) To find the marginal probability density functions of X and Y, we need to integrate the joint probability density function over the appropriate ranges. Since (X, Y) follows a uniform distribution over the unit disk D, the joint probability density function is constant within D and zero outside D.

The area of the unit disk is π, so the constant joint probability density function is 1/π within D. To find the marginal probability density function of X, we integrate the joint density function over the range of Y from -√(1 - x²) to √(1 - x²). This gives us the probability density function fX(x) = 1/π * 2√(1 - x²).

Similarly, integrating the joint density function over the range of X from -√(1 - y²) to √(1 - y²) gives us the marginal probability density function of Y: fY(y) = 1/π * 2√(1 - y²).

Since the marginal probability density functions are not constant, X and Y are not independent.

(b) The covariance of X and Y can be computed as Cov(X, Y) = E[XY] - E[X]E[Y]. Since X and Y are uniformly distributed on [-1, 1], their expected values are both zero. Thus, E[X]E[Y] = 0.

To compute E[XY], we can integrate the product of X and Y over the region D. However, since X and Y are symmetric with respect to the origin, their product is also symmetric. This means that the positive and negative regions of D will cancel out, resulting in E[XY] = 0.

Therefore, Cov(X, Y) = 0, indicating that X and Y are uncorrelated.

(c) To compute P(X ≤ Y), we need to determine the area of the region where X is less than or equal to Y within the unit disk D. This region corresponds to the quarter disk in the first quadrant.

The area of the quarter disk is 1/4 of the area of the unit disk, which is π/4. Since the area of D is π, we have P(X ≤ Y) = (π/4) / π = 1/4.

In mathematics, a vector is a quantity with magnitude and direction but no location. Acceleration and velocity are two examples of such numbers. A thing with both magnitude and direction is called a vector. A vector can be conceptualised geometrically as a directed line segment, the length of which corresponds to the magnitude of the vector, and the direction of which is denoted by an arrow. Size and direction are two independent characteristics of a quantity or phenomena known as a vector. The phrase also describes how these numbers are represented mathematically or geometrically. In nature, vectors may be found in electromagnetic fields, weight, momentum, force, and velocity.
